Description

Starting method and device and electronic equipment

Technical Field

The embodiment of the application relates to the field of terminals, in particular to a starting method, a starting device and electronic equipment.

Background

The battery arranged in the terminal can provide electric energy for the terminal so as to realize the starting and the operation of the terminal. The temperature greatly affects the performance of the battery, for example, the discharge power of the battery is reduced due to the influence of low temperature, and the terminal cannot be started at low temperature.

At present, when the terminal is started at a low temperature, the frequency of a Central Processing Unit (CPU) in the terminal can be reduced, so as to ensure that the terminal can be started and operated smoothly. However, the way of reducing the CPU frequency causes the performance of the terminal to be reduced, for example, the terminal has a long boot time and a low boot efficiency.

Disclosure of Invention

The embodiment of the application provides a starting method, a starting device and electronic equipment, which can reduce the starting time and improve the starting efficiency.

In a first aspect, an embodiment of the present application provides a boot method, where an execution main body for executing the boot method may be a terminal or a chip in the terminal, and the following embodiment takes the terminal as an example for description. In the method, the terminal comprises a battery and a CPU, wherein the terminal responds to a received starting instruction, is not connected with a power adapter, and can detect a first temperature of the battery. If the first temperature of the battery is lower than the first preset temperature, the terminal can reduce the CPU frequency to the preset frequency so as to reduce the power consumption of the CPU and ensure the smooth start-up of the terminal. In the process of starting the terminal, the terminal can acquire the attribute information of the battery, further adaptively adjust the parameters of the CPU according to the attribute information of the battery, and start the terminal according to the adjusted parameters of the CPU.

That is to say, in the embodiment of the present application, when the terminal is powered on, and when the first temperature of the battery is less than the first preset temperature, the terminal may first reduce the CPU frequency to the preset frequency, and then adaptively adjust the parameters of the CPU according to the attribute information of the battery, so as to improve the performance of the CPU, further improve the power-on efficiency, and reduce the power-on duration. When the terminal is started, the CPU is not kept at the preset frequency all the time, but parameters of the CPU are adjusted based on the attribute information of the battery, because the preset frequency is the lower frequency which is adjusted by the CPU when the terminal is started smoothly, and the temperature of the battery is increased in the using process of the battery, the CPU frequency in the adjusted parameters of the CPU is higher than the preset frequency, namely the performance of the CPU is improved, the starting efficiency can be improved, and the starting time length is reduced.

In an embodiment, after the frequency of the CPU is reduced to a preset frequency, the terminal may periodically acquire the attribute information of the battery, and then periodically acquire the maximum allowed power consumption that the battery can provide to the CPU according to the periodically acquired attribute information of the battery, and further periodically adjust the parameter of the CPU according to the periodically acquired maximum allowed power consumption. That is, the terminal can continuously adjust the parameters of the CPU based on the attribute information of the battery, so that the performance of the terminal can be improved as much as possible while ensuring smooth startup of the terminal.

In an embodiment, in response to receiving the boot instruction, the terminal may execute the boot operation according to the normal-temperature policy when the terminal is connected to the power adapter, where the normal-temperature policy may refer to the related description in the detailed description. Or, in an embodiment, when the terminal responds to receive the boot instruction, the terminal is not connected to the power adapter, and the first temperature of the battery is greater than or equal to the preset temperature, the terminal may also execute the boot operation according to the normal-temperature policy.

In an embodiment, the attribute information includes a third temperature, and when the third temperature is higher than the first preset temperature, the terminal may run a program of the BIOS, so as to ensure that the terminal can be successfully booted and run.

The following describes a process in which the terminal adjusts the parameters of the CPU according to the attribute information of the battery:

in an embodiment, the terminal may obtain the maximum allowed power consumption that the battery can provide to the CPU according to the attribute information of the battery, and further adjust the parameter of the CPU according to the maximum allowed power consumption. The terminal can obtain the current discharge power of the battery according to the attribute information of the battery, and further obtain the maximum allowed power consumption according to the current discharge power of the battery.

In an embodiment, the terminal may obtain the consumed discharge power of the battery according to the attribute information of the battery, and further use a difference value between a preset discharge power of the battery and the consumed discharge power of the battery as the current discharge power of the battery. Wherein the preset discharging power is a discharging power at a second preset temperature when the capacity of the battery is a maximum capacity, and the discharging power consumed by the battery includes: the temperature-lost discharge power and/or the capacity-lost discharge power, and the second preset temperature is greater than the first preset temperature.

In one embodiment, the temperature loss coefficient corresponding to the second temperature may be a constant value, or the temperature loss coefficient corresponding to the second temperature may be different according to the second temperature.

In one possible implementation, the attribute information of the battery includes: a remaining capacity, a maximum capacity, and a nominal capacity of the battery. The terminal may obtain the discharge power of the capacity loss according to a quotient of the maximum capacity and the nominal capacity, the remaining capacity, and a capacity loss coefficient corresponding to the remaining capacity.

In one possible implementation manner, the terminal may use a difference between a current discharge power of the battery and a power of other components in the terminal, which are components in the terminal except for the CPU, as the maximum allowable power consumption. In one embodiment, the power of the other components in the terminal may be a fixed value, or the power of the other components in the terminal may be related to the second temperature, and the remaining capacity, the maximum capacity, and the nominal capacity of the battery.

In a possible implementation manner, the EC writes the maximum allowed power consumption in a preset position of the CPU through the second GPIO port. And the CPU reads the maximum allowable power consumption at the preset position, and then the CPU adjusts the parameters of the CPU according to the maximum allowable power consumption.

In a possible implementation manner, after the EC writes the maximum allowed power consumption in a preset position of the CPU through the second GPIO port, the EC raises the level of the second GPIO port to a second preset level in response to successful writing of the maximum allowed power consumption. Correspondingly, the CPU responds to the fact that the level of the second GPIO port is the second preset level, and reads the maximum allowed power consumption at the preset position.

It is to be understood that the structure shown in fig. 1 does not constitute a specific limitation of the terminal. In other embodiments of the present application, the terminal may include more or fewer components than shown, or some components may be combined, some components may be split, or a different arrangement of components may be used. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

First, a terminal booting process in the prior art is described with reference to the structure of the terminal shown in fig. 1, fig. 2 is a schematic flow chart of terminal booting in the prior art, and referring to fig. 2, the terminal booting process in the prior art may include:

s201, responding to the terminal startup, and detecting the temperature of the battery by the EC under the condition that the terminal is not connected with the adapter.

And when the terminal is started, the EC is electrified. When the terminal is not connected with the adapter, the EC is powered by the battery, and when the terminal is connected with the adapter, the EC is powered by the external power supply connected with the adapter. It should be understood that the adapter in the embodiment of the present application refers to a device that can be connected to an external power supply to charge the terminal.

In the case where the terminal is not connected to the adapter, i.e., the terminal is not connected to the external power source, the EC may detect the temperature of the battery to determine whether the battery is at a low temperature. In one embodiment, the EC may detect the temperature of the battery via a temperature sensor. It should be understood that "low temperature" in the embodiments of the present application means that the temperature of the battery is less than a preset temperature, and the preset temperature (i.e., the temperature value for determining whether the battery is at the low temperature) corresponding to the battery may be different for different types of terminals.

S202, responding to the fact that the temperature of the battery is smaller than the preset temperature, and the EC controls the terminal to be started by adopting a first strategy.

And when the EC detects that the temperature of the battery is less than the preset temperature, the EC determines that the battery is at a low temperature, and the EC can adopt a first strategy to control the terminal to be started. It should be understood that the first strategy may be understood as a strategy when the battery is at a low temperature.

In the prior art, in an embodiment, the EC may interact with the CPU to reduce the frequency of the CPU, so as to reduce the power consumption of the terminal when the terminal is turned on, so that at a low temperature (the temperature is lower than a preset temperature), the battery can provide the power required by the CPU when the terminal is turned on, and the terminal is ensured to be turned on smoothly. Wherein the first policy is: the CPU frequency is reduced.

In the embodiment, the CPU frequency of the terminal is reduced, so that the terminal has poor performance in the whole starting process, and the problems of long starting time, starting blockage, blockage after starting and the like are caused. In an embodiment, the CPU frequency of the terminal is reduced, which may also affect the experience of the user using the terminal after the terminal is powered on, and the user experience is poor.

In the prior art, in an embodiment, the EC may interact with the CPU, so that the CPU sets parameters of the CPU based on fixed power consumption, and because the parameters of the CPU are fixed, the terminal response flexibility is low, and the user experience may also be affected. In such an embodiment, the first policy is: the CPU sets fixed parameters of the CPU.

S203, responding to the fact that the temperature of the battery is larger than or equal to the preset temperature, and the EC controls the terminal to be started by adopting a second strategy.

The temperature of the battery is greater than or equal to a preset temperature, namely the battery is at a non-low temperature, and the EC responds that the temperature of the battery is greater than or equal to the preset temperature and can adopt a second strategy to control the terminal to be started. It is to be understood that the second strategy may be understood as a strategy when the battery is at a non-low temperature (normal temperature).

In one embodiment, the second policy may also be understood as: the CPU can adopt the CPU frequency at normal temperature without reducing the CPU frequency so as to realize the startup of the terminal. It should be understood that the CPU frequency when the terminal is at a non-low temperature (i.e., the CPU frequency at a normal temperature) according to the embodiment of the present application may be changed according to the terminal.

For example, the CPU frequency may reach 4.4G when the desktop computer is not at low temperature, and the CPU frequency may reach 1.6G when the terminal such as the notebook computer is not at low temperature. When the temperature of the battery is lower than the preset temperature, the CPU frequency may be reduced to, for example, 400MHZ to 800MHZ (first policy).

As in the prior art, in order to ensure smooth booting of the terminal under low temperature, the frequency of the CPU needs to be reduced, and the CPU remains low frequency during the whole booting process of the terminal (even after the terminal is booted), which may result in long time for the whole booting process, a booting jam, and a jam after booting, and thus the user experience is low.

In the embodiment of the application, when the terminal is started at a low temperature, the EC and the CPU can interact in real time, the starting strategy is adjusted in real time based on the temperature of the battery, the parameters of the CPU are adaptively adjusted, the starting time length can be reduced on the basis of ensuring the smooth starting of the terminal, and the starting time delay can be reduced, so that the user experience can be improved.

On the basis of the structure of the terminal shown in fig. 1, the following describes a booting method provided in the embodiment of the present application with reference to a specific embodiment. The following several embodiments may be combined with each other and may not be described in detail in some embodiments for the same or similar concepts or processes. Fig. 3 is a flowchart illustrating an embodiment of a boot method according to the present application.

Referring to fig. 3, the boot method provided in the embodiment of the present application may include:

s301, the EC responds to the terminal startup and detects whether the terminal is connected with the adapter. If not, go to step S302, and if so, go to step S312.

When the terminal is started, the EC is powered on, and the EC can detect whether the terminal is connected with the adapter or not.

As shown in fig. 4, when the terminal is connected to the adapter, the adapter may be connected to the charging chip in the terminal, and when the terminal is not connected to the adapter, the charging chip is not connected to the adapter. When the adapter is connected with or disconnected from the charging chip, the charging chip can detect the change of the voltage, and the charging chip can inform the EC of the connection state of the adapter through the GPIO port (the GPIO port between the charging chip and the EC) in response to the detected change of the voltage, so that the aim of detecting whether the terminal of the EC is connected with the adapter is fulfilled.

For example, if the charging chip detects that the voltage of the charging chip increases to the output voltage (e.g. 5V) of the adapter, it may be determined that the charging chip is connected to the adapter, and at this time, the external power supply supplies power to the terminal, and the charging chip may pull up (or pull down) the level of the GPIO port to notify that the EC adapter is in the connection state. Accordingly, the charging chip can determine that the adapter is in a connection state based on the level pull-up of the GPIO port, namely the terminal is connected with the adapter.

If the charging chip detects that the voltage of the charging chip is reduced to a preset voltage (for example, less than 5V), it may be determined that the charging chip is disconnected from the adapter, at this time, the battery supplies power to the terminal, and the charging chip may pull down (or pull up) the level of the GPIO port to notify that the EC adapter is in an unconnected state. Correspondingly, the charging chip can detect that the adapter is in a disconnected state according to the level reduction of the GPIO port, namely the terminal is not connected with the adapter.

In one embodiment, because the charging chip adaptively pulls the level of the GPIO port up or down when the adapter is connected to the charging chip or disconnected from the charging chip, the EC may determine whether the terminal is connected to the adapter based on the specific value of the level of the GPIO port. For example, if the level of the GPIO port is a pulled-up level (e.g., a first level value), the EC determines that the terminal is connected to the adapter, and if the level of the GPIO port is a pulled-down level (e.g., a second level value), the EC determines that the terminal is not connected to the adapter. Wherein the first level value is greater than the second level value. In one embodiment, the GPIO port to which the charging chip and EC are connected may be referred to as a first GPIO port.

S302, the EC detects a first temperature of the battery.

The EC may detect a first temperature of the battery via a temperature sensor. In one embodiment, the EC may read the first temperature of the battery detected by the temperature sensor through the SMBUS connection. It should be understood that the terms first temperature, second temperature, third temperature, etc. in the embodiments of the present application are used to characterize the temperature of the battery detected by the EC at different times, and the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor as indicating or implying order.

And S303, in response to the first temperature of the battery being lower than a first preset temperature, the EC pulls down the level of the GPIO port connected between the EC and the CPU to a first preset level.

The first preset temperature may be preset, and the first preset temperatures corresponding to different types of terminals are different. In one embodiment, the first predetermined temperature may be, for example, 14 ℃. The first predetermined level is used to instruct the CPU to down-convert to a predetermined frequency, such as 400MHZ to 800MHZ for example.

In this embodiment of the application, in response to that the first temperature of the battery is lower than a first preset temperature, the EC may pull down the level of the GPIO port to which the EC and the CPU are connected, to the first preset level. In one embodiment, the EC may pull down the Prochot # signal carried by the GPIO port to instruct the CPU to down-convert to a preset frequency in response to the first temperature of the battery being less than a first preset temperature. It should be understood that Prochot is pulled out through one pin of the CPU and connected to the EC, and the EC can interact with the CPU by changing the signal of the pin corresponding to the Prochot.

In one embodiment, the GPIO port to which the CPU and EC are connected may be referred to as a second GPIO port.

S304, the CPU responds to the CPU power-on, detects that the level of the GPIO port connected with the EC and the CPU is a first preset level, and reduces the CPU frequency to a preset frequency.

In the process of starting the terminal, the EC is firstly electrified, and the CPU is then electrified. After the CPU is powered on, the level of the GPIO port connected between the EC and the CPU can be detected in real time, so that the CPU can reduce the frequency of the CPU to a preset frequency in response to the fact that the detected level of the GPIO port connected between the EC and the CPU is a first preset level.

S305, the CPU feeds back a response message to the EC through the PECI.

When the CPU is powered on, an Acknowledge (ACK) message may be fed back to the EC through the PECI, and the ACK message indicates that the CPU is powered on. It should be understood that the PECI is a private communication interface of the intel, and for a terminal provided with the PECI, the intel defines a communication flow through the PECI, in an embodiment, the EC and the CPU may communicate through the PECI, and after the communication is successful, the CPU may feed back a response message to the EC through the PECI, and a process of the EC and the CPU communicating through the PECI may refer to a description of the intel on the communication flow of the PECI. In one embodiment, the response message may be referred to as a communication success confirmation message.

In one embodiment, it is understood that if the EC and the CPU are not successfully communicating, the CPU feeds back a negative message (NACK) to the EC through the PECI to instruct the EC to re-communicate with the CPU. In one embodiment, the NACK may be referred to as a communication failure message.

S306, the EC responds to the received response message and detects the attribute information of the battery according to a preset rule.

In one embodiment, the preset rule may be: the EC periodically detects the attribute information of the battery, such as detecting the attribute information of the battery every 2 minutes. In an embodiment, the EC may detect the attribute information of the battery at regular time, for example, the attribute information of the battery is detected every 1 minute, 5 minutes, and the like after the EC is powered on.

The attribute information may include: a second temperature of the battery, a remaining capacity of the battery, a maximum capacity of the battery, a design capacity of the battery, and the like. It should be understood that the design capacity of the battery is the nominal capacity of the battery at the time of factory shipment, such as 60 Wh. The maximum capacity of a battery (i.e., the full charge capacity or actual capacity) is a variable value, and generally, the maximum capacity of a new battery is generally higher than the design capacity, but as the number of times the battery is charged and discharged increases, the battery ages and decays, and the maximum capacity gradually decreases. In addition, in a low-temperature environment, the battery activity is insufficient, and the maximum capacity is also reduced.

Wherein the EC may detect the second temperature of the battery through the temperature sensor. The EC can read parameters such as the remaining capacity of the battery, the maximum capacity of the battery, and the design capacity from the battery fuel gauge through the SMBUS.

And S307, the EC acquires the current discharging capacity of the battery according to the attribute information of the battery.

In the embodiment of the present application, the EC may obtain the consumed discharge capacity of the battery according to the temperature of the battery and/or the consumed capacity of the battery. And the EC acquires the current discharge capacity of the battery based on the discharge capacity when the battery is not consumed and the discharge capacity when the battery is consumed. In one embodiment, the discharge capability is used to characterize the discharge power of the battery.

The following describes the discharge capacity of the low temperature loss cell, and the discharge capacity of the capacity loss cell in order:

wherein the EC may obtain the discharge capacity of the low temperature-depleted battery according to the second temperature. In one embodiment, the EC may obtain the discharging capability of the low temperature-depleted battery based on a temperature difference between the second preset temperature and the second temperature and the low temperature loss coefficient. In one embodiment, the second predetermined temperature is indicative of normal temperature, such as 25 ℃. In one embodiment, the low temperature loss factor may also be referred to as a temperature loss factor.

In one embodiment, the EC may obtain the discharge capacity of the low temperature depleted battery using the following equation one:

F_HT=(T_P2-T₂)·C_Hformula one

Wherein, F_HTCharacterisation of the discharge Capacity of a Low temperature depleted Battery, T_P2Characterizing a second predetermined temperature, T₂Characterizing the second temperature, C_HAnd (5) characterizing the low-temperature loss coefficient.

In one embodiment, the low temperature loss coefficient may be a certain value. In one embodiment, the low temperature loss factor is related to a temperature difference between the second predetermined temperature and the second temperature, such that the higher the temperature difference between the second predetermined temperature and the second temperature, the higher the low temperature loss factor.

The EC may obtain the discharge capacity of the battery with capacity loss according to the remaining capacity of the battery and the maximum capacity of the battery. In one embodiment, the EC may obtain the discharge capacity of the capacity-depleted battery based on a quotient of the maximum capacity and the design capacity of the battery, the remaining capacity of the battery, and the capacity depletion factor.

In one embodiment, the EC may obtain the discharge capacity of the capacity-depleted battery using the following equation two:

In one embodiment, the capacity loss factor may be a certain value. In one embodiment, the capacity loss factor is related to a remaining capacity of the battery, and/or a quotient of a maximum capacity of the battery and a design capacity. Illustratively, when the capacity loss factor is related to the remaining capacity of the battery, the smaller the remaining capacity of the battery, the larger the capacity loss factor.

In one embodiment, the discharge capacity as battery depletion includes "discharge capacity of low temperature depleted battery F_HTAnd capacity loss of the battery_HC"to illustrate, EC is obtaining the discharge capability F of the low temperature loss battery_HTAnd capacity-depleted discharge capability F of the battery_HCThen, the discharge capacity F of the battery can be reduced according to the preset discharge capacity of the battery and the low-temperature loss_HTCapacity loss, discharge capacity F of the battery_HCAnd determining the current discharge capacity of the battery. The preset discharge capacity of the battery is the discharge capacity of the battery when the battery is at the second preset temperature (normal temperature) and the capacity of the battery is the maximum capacity. In one embodiment, the preset discharge capability may be referred to as a preset discharge power.

For example, the EC may use the preset discharge capacity minus the discharge capacity of the battery with low temperature loss and the discharge capacity of the battery with capacity loss as the current discharge capacity of the battery, and the current discharge capacity of the battery may be obtained based on the following formula three:

F_NOW=F_C-F_HT-F_HCformula three

Wherein, F_NOWCharacterizing the current discharge capacity of the cell, F_CAnd characterizing the preset discharge capacity.

S308, the EC acquires the maximum allowable power consumption of the CPU according to the current discharging capacity of the battery.

Maximum allowed power consumption characterization of the CPU: the terminal can provide power consumption corresponding to the maximum power of the CPU.

After the EC obtains the current discharging capability of the battery, the EC can subtract the power provided by the battery to other components in the terminal, and the rest is the power provided by the battery to the CPU. In one embodiment, the power provided by the battery to other components in the terminal may be preset in the EC. In one embodiment, the power provided by the battery to other components in the terminal by the battery used in the embodiments of the present application may be understood as "the maximum power required by other components".

In an embodiment other components in the terminal like a display, a hard disk, etc.

In one embodiment, the power that the battery can provide to the CPU can be obtained using the following equation four:

Wherein, F_FORCPUCharacterizing the power that the battery can supply to the CPU, F_otherThe power supplied by the battery to other components in the terminal is characterized. It is understood that F_otherMay be a certain value, different "other parts" in different types of terminals, corresponding to F_otherThe value of (c) is different.

After the EC obtains the power that the current battery can provide to the CPU, the EC may obtain the maximum allowed power consumption of the CPU based on the power that the current battery can provide to the CPU and the discharging efficiency of the battery.

In one embodiment, the maximum allowed power consumption of the CPU may be obtained using the following formula five:

E_CPU=F_FORCPUc formula five

Wherein E is_CPUCharacterizing maximum allowed work of a CPUAnd c represents the discharge efficiency of the battery. Illustratively, the discharge efficiency of the cell is, for example, 90%.

S309, the EC writes the maximum allowed power consumption of the CPU into a preset position of the CPU through the PECI.

After the EC obtains the maximum allowed power consumption of the CPU, the EC may write the maximum allowed power consumption of the CPU into a preset position of the CPU through the PECI.

In one embodiment, the EC may send a write instruction to the CPU, including the maximum allowed power consumption of the CPU. And the writing instruction is used for instructing the CPU to write the maximum allowable power consumption of the CPU into a preset position of the CPU.

Accordingly, the CPU may write the maximum allowable power consumption of the CPU into a preset position of the CPU in response to the write instruction. It should be understood that the CPU successfully writes the maximum allowed power consumption of the CPU into the preset position of the CPU, and a message that the writing is successful may be fed back to the EC. If the CPU fails to write the maximum allowed power consumption of the CPU, a write failure message may be fed back to the EC, where the EC may continue to interact with the CPU in response to receiving the write failure message, and repeatedly try to write the maximum allowed power consumption of the CPU until the write is successful.

And S310, in response to the successful write-in of the maximum allowed power consumption of the CPU, the EC pulls up the level of the GPIO port connected with the EC and the CPU to a second preset level.

When the maximum allowable power consumption of the CPU is successfully written, the EC pulls up the level of the GPIO port connected with the EC and the CPU to a second preset level, and the second preset level is used for indicating the CPU to adaptively adjust the parameters of the CPU according to the maximum allowable power consumption of the CPU so as to avoid the condition that the CPU frequency is always in the preset frequency to influence the performance of the terminal and further influence the user experience. The second preset level is greater than the first preset level.

In one embodiment, the EC may pull up the Prochot # signal carried by the GPIO port to instruct the CPU to adjust the parameters of the CPU.

S311, the CPU responds to the fact that the detected level of the GPIO port connected with the EC and the CPU is a second preset level, the parameters of the CPU are adjusted according to the maximum allowable power consumption of the CPU at a preset position, and the CPU is started up according to the adjusted parameters.

The CPU can determine that parameters of the CPU need to be adjusted adaptively in response to detecting that the level of the GPIO port connected with the EC and the CPU is a second preset level. The CPU can read the maximum allowable power consumption of the CPU from a preset position, and then parameters of the CPU are adjusted according to the maximum allowable power consumption of the CPU so as to start the computer. That is, in the process of executing the boot operation by the CPU, the parameters of the CPU may be adaptively adjusted, and the boot operation is executed by the adjusted parameters of the CPU, so as to boot the terminal.

It should be understood that the PECI in the embodiment of the present application is a private communication interface of intel, and for a terminal provided with the PECI, the intel sets a protocol and a command of a CPU parameter in the PECI, which may refer to the related description of the existing PECI. The CPU may adjust parameters of the CPU based on intel's DTT (dynamic tuning technology) technology in response to reading the CPU's maximum allowed power consumption from a preset location. In one embodiment, the PECI bus provides a general interface for the EC of the intel to control the CPU power, and the EC can adjust the parameters of the CPU according to the rule agreed by the intel by a PECI write command and setting performance parameters such as PL1/PL2/PL 4.

In one embodiment, the parameters of the CPU may include, but are not limited to: power limit 1 (power limit 1, PL 1), PL2, PL3 and PL 4. In one embodiment, PL1 is a threshold for average power, typically set to be less than or equal to Thermal Design Power (TDP) power. PL2 is a threshold and if the PL2 power of the CPU exceeds this threshold, the PL2 fast power limit algorithm will attempt to limit the peak above PL 2. PL3 is a threshold and if the PL3 power of the CPU exceeds this threshold, the PL3 fast power limit algorithm will attempt to limit the duty cycle above the spike of PL3 by reactively limiting the frequency. PL4 is a limit that cannot be exceeded and the PL4 power limit algorithm will preferentially limit the frequency to prevent spikes above PL 4. It should be understood that, in general, PL1 is equal to TDP, PL2 is the power wall of the processor in the turbo state, and the PL2 power of the CPU cannot exceed it. There are also PL3 and PL4, both of which are instantaneous power consumption of the processor, both of which are generally preset and cannot be manually adjusted by the user.

In one embodiment, it can be understood that: the maximum allowable power consumption of the CPU and the parameter of the CPU are defined by the DTT technology of intel, and the CPU may adjust the parameter of the CPU based on the maximum allowable power consumption of the CPU and the mapping relationship.

In one embodiment, because the terminal may detect the attribute information of the battery according to a preset rule (e.g., periodically or periodically), the terminal may continuously perform S307 to S309 accordingly. It should be noted that after the EC writes the maximum allowed power consumption of the CPU into the preset position of the CPU through the PECI for the first time, and in response to the successful writing of the maximum allowed power consumption of the CPU, the level of the GPIO port to which the EC and the CPU are connected may be pulled up to the second preset level, and after the subsequent EC performs S307-S309 to obtain the maximum allowed power consumption of the CPU, the EC may write the maximum allowed power consumption of the CPU into the preset position of the CPU through the PECI without performing "pull up the level of the GPIO port to which the EC and the CPU are connected to the second preset level in response to the successful writing of the maximum allowed power consumption of the CPU". At this time, the level of the GPIO port connected between the EC and the CPU is always the second preset level, so that the CPU can be triggered to detect the preset position in real time to read the latest maximum allowable power consumption of the CPU, and the CPU can be adaptively adjusted in parameters. In the embodiment, after the EC raises the level of the GPIO port connected between the EC and the CPU to the second preset level, the maximum allowed power consumption of the CPU is obtained subsequently, the maximum allowed power consumption of the CPU can be written into the preset position of the CPU through the PECI, and the operation of raising the level of the GPIO port connected between the EC and the CPU to the second preset level is not executed, so that the signaling interaction can be reduced, and the resources are saved.

And S312, the EC controls the terminal to be started by adopting a second strategy.

S312 may refer to the description related to S203.

In an embodiment, from the perspective of executing the booting method provided in the embodiment of the present application by using the terminal as an execution main body, the above S301 to S311 may be simplified as shown in fig. 5.

In an embodiment, it is noted that after the EC obtains the first temperature in S302, if the EC detects that the first temperature of the battery is greater than or equal to the first preset temperature, the CPU parameters may be controlled according to a normal temperature control strategy, and reference may be made to the relevant description in S203. In one embodiment, the ambient temperature control strategy may be understood as a second strategy.

In the embodiment of the application, when the terminal is started at a low temperature, the CPU frequency is reduced, the power consumption of the CPU can be prevented from being too high when the CPU is powered on, the system is powered off due to the fact that the power consumption exceeds the discharging capacity of a battery instantly, the terminal can be started smoothly, the EC can detect the attribute information of the battery according to the preset rule, and then the EC can adaptively control the CPU to adjust the CPU parameters based on the attribute information of the battery.

In an embodiment, in a scenario where the terminal is turned on at a low temperature, the EC may detect attribute information of the battery according to a preset rule, and when the EC detects that the temperature of the battery is greater than or equal to a preset temperature, that is, when the EC determines that the terminal is not at the low temperature, the EC may write a normal temperature control policy (or write the maximum allowable power consumption of the CPU corresponding to the normal temperature scenario) in a preset position of the CPU through the PECI, so that the CPU may control parameters of the CPU based on the normal temperature control policy.

Referring to fig. 6, after S311, S313-S314 may be further included:

s313, the EC writes, by the PECI, the maximum allowable power consumption of the CPU at the third temperature at the preset position of the CPU in response to detecting that the third temperature of the battery is greater than or equal to the preset temperature.

It should be understood that, for the method for obtaining the maximum allowed power consumption of the CPU at the third temperature, reference may be made to the description about obtaining the maximum allowed power consumption of the CPU at the second temperature in S307-S308, which is not described herein again.

And S314, the CPU adjusts the parameters of the CPU to operate according to the maximum allowable power consumption of the CPU at the third temperature.

It should be appreciated that the CPU may adjust parameters of the CPU to operate based on a maximum allowed power consumption of the CPU at the third temperature. In an embodiment, when the third temperature of the battery is greater than or equal to the preset temperature in the process of the CPU executing the boot operation, the CPU may adjust parameters of the CPU according to the maximum allowable power consumption of the CPU at the third temperature, so as to operate according to the adjusted parameters of the CPU to perform the boot operation.

In an embodiment, after the terminal is powered on, if the third temperature of the battery is greater than or equal to the preset temperature, the CPU may adjust parameters of the CPU according to the maximum allowed power consumption of the CPU at the third temperature, so as to operate according to the adjusted parameters of the CPU, so that the terminal operates normally. In this embodiment, the terminal is not always at the preset frequency after being powered on, but runs based on the attribute information of the battery or according to the parameters of the CPU corresponding to the maximum allowed power consumption of the CPU at the third temperature, so that the performance of the terminal after being powered on can be improved, and the problem of stuttering after being powered on is avoided.

In an embodiment, the CPU detects that the maximum allowed power consumption of the CPU is the maximum allowed power consumption of the CPU at normal temperature, and the CPU may execute a program of a Basic Input Output System (BIOS) to adaptively adjust parameters of the CPU, which may specifically refer to the above-mentioned description about the second policy and the related description about the program operation using the BIOS in the prior art at normal temperature.

In the embodiment of the application, in the process of starting the terminal or after the terminal is started, the EC may further detect attribute information of the battery according to a preset rule, and when the third temperature of the battery is greater than or equal to the preset temperature, that is, the battery is at a non-low temperature condition, the EC may interact with the CPU, so that the CPU controls parameters of the CPU to operate according to a normal-temperature control strategy.
